Why do we use inductor in buck converter?
Answer : In a **buck converter**, the inductor plays a key role in the operation and performance of the circuit. Here's why it is used: 1. **Energy Storage**: The inductor stores energy ... smooth the current, and it enables the converter to step down the voltage efficiently while minimizing current ripple....
